A unique new title dedicated to adverse possession, this book focuses on the proofs, ie animus possidendi and acts of possession by the squatter and the implications of squatting on leasehold land, registered land, co-owned land, land subject to a trust, a future interest or a mortgage. The author examines in detail the use of the doctrine in the context of unadministered estates or informal transactions, and also includes a review of recent proposals for reform and the potential impact of these reforms.
